In the world of veterinary medicine, not all healthcare workers are confined to the cool and controlled temperatures of indoor clinics. Equine practices, livestock medicine, mobile veterinary services, and in-home hospice care and euthanasia often place veterinary professionals outdoors and directly in the elements. As temperatures rise, so does the risk of heat-related illness. One of the most vital tools in preventing heat stress? Hydration.
Hydration – A Critical Safety Protocol
The National Institute for Occupational Safety and Health (NIOSH) recommends that workers drink 1 cup (8 ounces) of water every 15 to 20 minutes when working in hot conditions. OSHA reinforces this guidance by requiring employers to provide cool water in a location that is familiar to workers, near the work area, easily accessible, and in sufficient quantity for the entire work shift.
This may sound simple, but implementing this in a veterinary setting can be challenging. Medical environments are bound by infection control standards and regulatory compliance. Staff are not allowed to eat or drink in areas where patients are treated, hazardous chemicals are stored, or biological waste is present. For veterinarians in mobile and farm-based settings, this means planning ahead to ensure hydration opportunities are safe, sanitary, and compliant with standards.
What Temperature Should Water Be?
According to NIOSH, drinking water should be cooler than 59 degrees Fahrenheit. While ice-cold water may seem refreshing, it can be difficult to consume in large quantities. Conversely, lukewarm or hot water is less appealing and may be avoided altogether. The key is to keep water cool enough to encourage steady consumption throughout the day. In some states, like California, employers are required to provide cool, fresh water to employees free of charge. A spokesperson from the California Division of Occupational Safety and Health confirms this mandate, emphasizing the importance of accessibility and quality.
The Dangers of Dehydration
Dehydration doesn’t just reduce comfort—it endangers health and safety. When the body lacks adequate fluids, physical and cognitive performance suffers. Dehydrated employees are at a significantly greater risk of illness and injury. They may experience:
- Headaches
- Fatigue
- Lightheadedness or confusion
- Flushed, red skin
- Muscle cramps
- Heat intolerance or chills
- Dark-colored urine
Any of these symptoms should be considered a warning sign to stop and hydrate immediately.
Hydration as a Culture
Preventing heat stress begins before the workday starts. Encourage team members to hydrate before, during, and after their shifts. Supervisors and team leads should normalize hydration breaks and model good behavior. Make water easily accessible, whether that means installing refill stations, offering cooler jugs on mobile units, or designating safe zones where hydration is permitted.
Veterinary professionals face unique challenges and serve patients in varied and often demanding environments. Preparing for heat is more than just a matter of comfort – it’s a matter of safety, performance, and well-being. Employers who take hydration seriously will not only reduce risks but also build a workplace culture rooted in health and care for the caregivers.
